To extend the deadline for filing your tax ID number, please log in to your Penta account and go to the "Administration" menu item in the "Tax & Residency" tab.

Then click on "Start", select the checkbox "My tax ID has not yet been issued" and click on "Save". 

This way, your account will not be locked until you receive your tax ID from the tax authority.
